Configuration Examples for IP SLAs TCP Connect Operations
The following example shows how to configure a TCP Connection-oriented operation from Device B to the Telnet port (TCP port 23) of IP Host 1 (IP address 10.0.0.1), as shown in the “TCP Connect Operation” figure in the “Information About the IP SLAs TCP Connect Operation” section. The operation is scheduled to start immediately. In this example, the control protocol is disabled on the source (Device B). IP SLAs uses the control protocol to notify the IP SLAs responder to enable the target port temporarily. This action allows the responder to reply to the TCP Connect operation. In this example, because the target is not a Cisco device and a well-known TCP port is used, there is no need to send the control message.
Device A (target device) Configuration
configure terminal
ip sla responder tcp-connect ipaddress 10.0.0.1 port 23
